To be honest, the "added shiny" isn't really enough to tempt me to get the Trezor T. I'm a big fan of the K.I.S.S. principal... But good on Trezor, I'm sure it'll appeal to the "ZOMG colour touchscreen!!?!" crowd

What does concern me... will Trezor run the "only add new coin support to the new device" play? ie. Stop development on the older device?

The Trezor T has an advantage over original Trezor due to the new platform which is supposed to make it easier to integrate new coins. While your current Trezor will still work fine you are right, there may be coins that are only supported on the new Trezor T. It has a faster processor and new firmware. I already ordered mine. Consider Ledger no longer supports the Unplugged or original Nano. I find it remarkable that my Trezor from 2014 still works fine. You can't stop progress.

It depends on what you exactly mean. You can use one pin to access all your separate accounts. Your receiving address changes if you used the address before. If you want to hide your real bitcoins then you should use passphrases. They are much safer because you are less vulnerable to $5 wrench attack. You can send for example $100 in BTC to your "fake" passphrase accounts and hold the rest of your fortune on a normal one.

I'm satisfied with Ledger Nano S. However, it looks like managing PGP keys is easier on Trezor. I decided to order Trezor T because it has bigger screen than Nano and has microsd support. I have to keep some files encrypted so it will be more convenient for me. Anyone here interested in a review by me when I get it?

Yes... you can add multiple "accounts" within Bitcoin. Each account creates separate and unique addresses from the others and you can label them (and use different colours) to differentiate the accounts from one another.

The balance of each account is separate from the other accounts, and you cannot combine coins from separate accounts into one transaction.

As mentioned previously, you can also use different passphrases to generate completely different wallets, which are also separate from each other, but you can't "see" them together at the same time within the ledger bitcoin wallet chrome app.

i personally will try the digital bitbox since it's security on the hardware side is perfect, meanwhile it's still in development mode which is good because in the future, digital bitbox will support other alts, and it's price will soon be expensive.

when you are very serious on security, you can check out digital bitbox.

I have a Digital Bitbox and don't use it as it only supports bitcoin and ethereum (ETH, ETC and ERC20 tokens.) Original Trezor still has the best user experience. Nano S has only so much memory you can only have four or five coin apps open at a time. I also think Trezor did a great job with making splitting off your BCH and BTG as easy as possible. Support for KeepKey seems to be fading away you still can't directly split BCH and BTG on a KeepKey. Remember Case hardware wallet? They were in business for a year then closed shop; starting to wonder if same will happen with KeepKey.
